On some points:

Papers for IWP9 and macros:

concerning the papers: I will add during September 2025 a variable
to TeX (in fact Prote) in order to be able to process macro definition
with the escape character being the beginning of the line ('/^\./') for
roff compatibility (handling utf-8 can also be done with minimal cost,
but I need to fix my ideas about the fonts handling; so I let this
mature). So even a *roff like macro package could be treated with
TeX/Prote as layout engine;

Making money:

Since PDF is an ISO spec, a lot of entities
mandate its use, requiring to digitally sign a PDF, keeping the
PDF "vectorial" (not to scan a signed paper, wrapping the raster image
in PDF, or not even to add an image of signature on a "vectorial"
PDF). 

This is "open", right? Yes, but you will have a hard time finding an
open (not AGPL) PDF library able to do it. So a lot of companies milk
the customers requiring whether to pay for every digitally signed PDF,
or to , or to engage for a monthly subscription.

Signing a PDF is neither rendering the PDF, nor implementing the whole
PDF: the signature is appended to the file, the xref being rewritten
(one reads the PDF from the end, searching for the last '/^%EOF\n/' to
get the offset to the xref that can reach out to previous xref.

Proposing such a service with reasonable prices, adding the
possibility to choose where a text about the signature will appear
(generally, such a text appears at the most inconvenient place when
displaying the file), could work.

PDF signing is interesting.  I've been doing a bunch of PDF processing
lately using Russ's golang library.  Adding anew block should be easy.

We have also been talking about signing the PDFs from iwp9 so we can also
distribute the source without fear of imposter papers.
